So far, I have been successful in ignoring those warnings and just
going ahead and doing the fdisk / bsdlabel / newfs.   After that the
warnings seem to stop and everything works OK.   It makes me wonder
why those messages still come out on new disks, if they aren't meaningful,
bit I don't know the whole deal about it.

Geometry seems to be virtual and the OS does its own thing once it
gets out from under BIOS processing.
